upgrade with Foil faced insulation?
I have about 35 ' of exterior wall in my family room coverred with panelling, not big enough to make it practical to call a contractor for spray foam, but I want to remove the inside paneling, re-insulate and drywall at some point soon without diisturbing the adjacent walls.
This wall is 2 x 4 with brick exterior so I want to take advantage of the inside access. I would like to furr it out for added insulation but have an exterior door sitting 1" off the corner of the wall at present. I think the current insulation, 35 years old is likely between R10 and R12.
Any thoughts on using foil faced insulation on the inside of the cavities or suggestions on how to tackle this one
